Hi,
I am getting the below for this domain. The bcamyview.com is not a valid domain so the error is correct. How can I whitelist either the domain or IP address for the senders domain. So far I have “fixed” it by adding the IP as a trusted network which is obviosuly not ideal but fine in the short term.
NOQUEUE: reject: RCPT from dcmailrelay.zellis.com[152.114.220.10]: 450 4.1.8 donotreply@xxx.com: Sender address rejected: Domain not found; from=donotreply@bcamyview.com to=xxx@xxx.co.uk proto=ESMTP helo=<dcmailrelay.zellis.com>
Many Thanks in advance
